Out of Memory Errors

I love this game, its fantastic but something is worrying me.

It crashes. Randomly.

All I get is a big fat error log full of numbers and "Out of Memory" I've not seen anything like this on the Guild Wars 2 help pages, FAQ or FB page and I'm wondering if anybody is experiencing the same thing.

I've got 4GB Ram and a GeForce GTX 275 - it runs fine no framerate issues or anything. I've even tried lowering my graphics but it will still crash randomly.

Alright Its been 2 full days and no error, so what I did to fix this is.
Changed my pagefile onto my windows partition and change it to 3000mb-4000mb so now there is no way it could lie and say out of memory.

I might be wrong here but most Anti-Virus Programs that feature Real-Time protection have separate processes and disabling the Program most likely leaves the Real Time protection to still run in the background. You could try adding gw.exe to the exceptions if possible, might have to do with the "streaming" technology (If GW2 uses that, that is.)

Also, I stumbled over this, might or might not help your case but it's worth taking a look I presume.

I recall ArenaNet stating in one of the stress tests that a 32-bit OS was limited/not supported for the 'High-Res' character checkbox in graphics options. Their reason being that the memory draw would be too great, causing out of memory errors, random crashing, etc. I'd suggest trying the absolute lowest graphics setting, newer drivers (if you haven't already) and contacting ArenaNet support.
